Cook Strawn 85s/86s Pooled Unit #77 (API 42-417-39118) is a well in Shackelford County operated by Stasney Well Service LLC, completed November 11, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 14, 2010, permitted to 4,000 ft.
It was permitted by Stasney, H. R. & Sons, Ltd. and has since transferred to Stasney Well Service LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Coleman Junction, Dothan Ls, Tannehill, Breckenridge Ls.
Its lease has reported 66.5K barrels of oil and 67.1K mcf of gas since May 2010, last reporting in July 2026. The lease carries 12 wells, so these are lease totals, not this well alone.
